Product Information

The DZ5000/5200LS-QX Industrial Chiller is a powerful cooling machine designed for industrial use. It is equipped with a temperature controller, flow alarm, power switch, air inlet with filter gauze, power socket with fuse, alarm output terminal, cooling water outlet, cooling water inlet, air outlet, water level gauge, and outfal. The chiller operates on a voltage range of 200-250V (100-130V for AC110V model) and has an average operating current of up to 6-10 amps (10-15 amps for AC110V model). The chiller is designed to work with a power frequency of either 50Hz or 60Hz.

Product Usage Instructions

Ensure proper electrical connections: Make sure the power supply and electrical outlet are in good contact and the earth wire is firmly grounded. The instantaneous operating current of the chiller can be high, so ensure the power supply can handle it.
Maintain stable voltage: The refrigeration compressor is sensitive to power supply and voltage fluctuations. Ensure there is a stable and normal voltage supply within the range of 200-250V (100-130V for AC110V model). Customization is available for wider voltage ranges.
Choose the correct power frequency: Select the model with a power frequency of either 50Hz or 60Hz according to the actual circumstances.
Ensure proper ventilation: Make sure the air inlet and air outlet have good ventilation. Keep at least 30cm of space between obstructions and the air outlet at the back of the cooler. Leave at least 8cm of space between obstructions and the side air inlet.
Clean the filter screen regularly: It is essential to clean the dust gauze regularly to prevent blockage and potential breakdown of the chiller.
Manage condensate water: I n high humidity environments, condensate water may generate on the surface of water circular pipes and cooled components. If this occurs, adjust the water temperature or keep the pipes and cooled parts warm.
Professional use only: This appliance is intended for professional use only. It should not be used by children or persons with reduced physical, sensory, or mental capabilities unless supervised or instructed.

Cautions

Please ensure that the power supply and electrical outlet are in good contact and the earth wire must be firmly grounded!
Although the average operating current of the chiller is small, the instantaneous operating current could be up to 6 ~ 10amps sometimes (The instantaneous operating current of models of AC110V power supply are possible to be up to 10 ~ 15amps).
Please make sure there is stable and normal voltage for the working chiller!
As the refrigeration compressor is more sensitive to the power supply and voltage, so the operating voltage of our standard product is 200 ~ 250V (110V model is of 100 ~130V). If you do need a wider operating voltage range, customization is available for us.
Unmatched power frequency can cause the chiller damage!
Please choose the model of 50Hz or 60Hz according to actual circumstances.
To protect the pump, it’s strictly forbidden to run the chiller without water in the storage water tank!
The new machine is packed after draining the whole water in the tank, so please make sure the tank has water inside before the machine starts, otherwise, it’s easy to have the pump damaged. When the water level is below the green
(NORMAL) range of the water level gauge, the cooling capacity of our chiller will go down slightly. Hence please ensure the water level is within the green
(NORMAL) range. To drain through a circulating pump is strictly prohibited!
Please be sure that the air inlet and air outlet are in good ventilation!
There must be at least 30cm from obstructions to the air outlet which is in the back of the cooler and should leave at least 8cm between obstructions and the side air inlet.
The filter screen must be regularly cleaned!
It’s essential to unpick and wash the dust gauze, or the serious blockage will cause breakdown of the chiller.
Please pay attention to the effect of the condensate water!
With greater ambient humidity, when the water temperature is lower than the ambient temperature, the condensate water will generate on the surface of water circular pipes and the cooled components. If above circumstance appears, it is recommended to set a higher water temperature or keep pipes and cooled parts warm.
Professional use only!
The appliance is not to be used by children or persons with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction, children are being supervised not to play with the appliance!

Parts introduction

Installation

It is very simple to install this industrial cooling machine. The installation for the first time of the new machine can be carried out by following steps:

Open the package to check if the machine is intact and all the necessary accessories are completed.
Open the injection port to feed cooling water. (Do not let the water spill over!) Observing the water level gauge and adding water slowly, be careful not to have the water overflowed! For the cooling of carbon steel equipment, the water should be added an appropriate amount of cooling water additive
(anti-corrosion water aqua). Working in the cold north area, it’s better to use noncorrosive antifreeze fluid.
According to system conditions, please connect the water inlet and outlet pipe well.
Plug in the power, and turn on the power switch. (Do not start up without water in the water tank!)
Power switch is turned on, and the circulation pump of the chiller starts working. The first time of operation may cause more bubbles in the pipe leading to a flow alarming occasionally, but running for a few minutes later, it will go back to normal.
After the first boot, you must immediately check whether the water pipe leaks.
Power switched on, if the water temperature is below the set value, it is normal that fans and other components of the machine do not work. The temperature controller will automatically control the working conditions of the compressor, magnetic valve, fans, and other parts based on the set controlling parameters.
As it takes a longer time to start over the compressor and other components, according to different conditions, the time is range from seconds to minutes, so do not turn off the power again frequently.
Check the water level in the water tank.
The first startup of the new chiller empties the air in the water pipe, leading a slight water level decline, but in order to keep the water level in the green area, it’s allowed to add adequate water again. Please observe and record the current water level, and inspect it again after the chiller running for a period of time, if the water level drops obviously, please re-inspect the water pipeline leakage.
Adjust parameters of temperature controller.
CW-5000/5200 series uses an intelligent thermostat. Normally users do not need to adjust it. If it is really necessary, please refer to page 15, “Operating status and parameters adjustment.”

Operation status and parameters adjustment

The new T503 intelligent temperature controller does not need to adjust the controlling parameters under normal circumstances. It will self-adjust controlling parameters according to room temperature for meeting equipment cooling requirements.
The new T504 intelligent temperature controller is selected constant temperature control mode as factory setting with the water temperature at 25℃. Users can adjust it as needed.

T503 and T504 controllers are of the same functions and structure except for factory parameters setting.

If no button is pressed within 20 seconds, the controller will automatically exit the parameters setup without saving the modified parameters.
  Note:
- During parameters setting condition, the system still runs under original parameters.
- Under the temperature control mode, the water temperature is controlled by (F0) parameters;
- Under Intelligent control mode, the water temperature will be automatically adjusted according to temperature changes. The temperature difference is commanded by (F1) parameter.
Advanced parameters adjustment case

Case 1: cooling water temperature is controlled by intelligent mode. Requiring water temperature to be between 25℃ to 31℃. The ambient temperature keeping constant, when the set water temperature is 3℃ lower than the ambient, the fluctuation will not exceed ± 0.5 ℃. There will be an alert when the water temperature is 10 ℃ lower or higher than the target. (e.g. when the ambient temperature is 30.0℃, cooling water temperature is between 27.5℃ to 26.5℃, if the ambient temperature is up to 30.5℃, the water temperature will be between 28.0 ℃ to 27.0℃.)
Case 2 : cooling water temperature is controlled by constant mode. Requiring water temperature is constant at 28℃, and the fluctuation does not exceed ±2℃. The alarm of over high water temperature will be on when the water temperature is 5℃ higher than normal, and the alarm of over low water temperature will be on when the water temperature is 10℃ lower than normal.
Case 3: cooling water temperature is controlled by constant mode. Requiring water temperature is constant at 25℃, and the fluctuation does not exceed ±1℃. The over-high water temperature will be on the water temperature is higher than 30℃, and the alarm of over low water temperature will be on when the water temperature is lower than 10℃. (No matter what is the ambient temperature, the cooling water temperature is constant from 24.0℃ to 26.0℃)

Flow alarm and output ports

In order to guarantee the equipment will not be damaged while cooling water circulation is out of control, 5000/5200series chillers possesses an unique low flow alarm protection.
